Being able to store vegetables for a long period of time will provide you with a diverse diet and it will save your from eating the same food over and over again. Blanching vegetables is a skill easy to master and everyone can do it.
Blanching is a cooking process wherein the foods (usually vegetables or fruits) are plunged into boiling water, removed after a precise time interval and placed under cold running water or immersed into iced water to stop the cooking process. Blanching slows or stops the enzyme action which is responsible for the loss of flavor, color and texture in vegetables or fruits. Basically, you are stopping the process of aging and spoilage so that the vegetables will keep better in the freezer.
This is a simple food preservation method that involves freezing the vegetables, right after the blanching process stops. The trick is to know exactly how much time you need to blanch the food and the blanching time varies with the variety and size of vegetables.

If you under-blanch the vegetables, the activity of the enzyme is stimulated and it will be worse than not blanching them. On the other hand, if you over-blanch the vegetables, it will cause a loss of flavor, color, vitamins and minerals.
An easy to follow blanching method:
First wash, drain and sort the vegetables Trim and cut the vegetables as for cooking fresh You will need to use one gallon of water per pound of prepared vegetables. If you plant to blanch leafy greens, you will need two gallons of water Put the vegetables into the blancher of your choice (a perforated metal strainer or a wire basket will work just great) and lower into boiling water Cover the blancher with a lid and count the blanching time as given in the direction below The heat must be kept high for the entire blanching time Cool he vegetables immediately in ice water for the same time used in blanching. You will have to stir the vegetables a few times to make sure they are all soaked evenly. Drain the vegetables thoroughly and place them into containers. Place the containers into the freezer and separate all the containers by about an inch so that cooling takes place quickly. The following day stack everything together so that you can save space
